   Replaced below because it only covered the ingredient-page sidebar
   (.two-col/.sidebar): the story pages use different wrapper class names
   (.story-two-col/.story-sidebar) and never actually got the "stack under
   main content" treatment. It also didn't touch .mi-btn CTAs, left dead
   nav-colored links looking clickable, and printed the dark-green/photo
   page headers with white text and no background-safety net (most
   browsers don't print background-images/colors unless the reader opts
   into "background graphics" in the print dialog, which would leave that
   white text invisible on white paper).
